Is it possible to use something other than a listview as sliding drawer in drawerlayout

I would like to have for example a LinearLayout or a RelativeLayout sliding from the left of the screen instead of a lone ListView.

I tried to use à LinearLayout with android:layout_gravity="start" and i had this error at runtime:

ClassCastException: android.widget.LinearLayout$LayoutParams cannot 
be cast to android.support.v4.widget.DrawerLayout$LayoutParams

here's the layout file:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    >

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <LinearLayout 
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:orientation="vertical">

        <ImageView 
            android:id="@+id/ivwLogo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/video_icon"
        />

        <ListView 
            android:id="@+id/left_drawer"
            android:layout_width="320dp"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp"
            android:background="@android:color/white"
        />

    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

Thanks

Make sure you pass correct object (your LinearLayout called mDrawerLinear) for methods like isDrawerOpen, closeDrawer etc. This line solved my ClassCastException:

boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerLinear);

This will work if you move both the android:id="@+id/left_drawer" (or create a new id) and set the gravity.

The id move (or new one) is so the reference is correct so you call closeDrawer() on it and not the child views.

But most importantly, the DrawerLayout requires that element to have a android:layout_gravity set on it, as you mentioned.

Finally, you need to call close closeDrawer() on the base view, the one with the required gravity.

Example:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white">

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <LinearLayout 
        android:id="@+id/left_drawer"
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:orientation="vertical">

        <ImageView 
            android:id="@+id/ivwLogo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/video_icon" />

        <ListView 
            android:id="@+id/left_drawer_child"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp"
            android:background="@android:color/white" />

    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

In code:

DrawerLayout mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout)
LinearLayout mDrawerLinear = (LinearLayout) findViewById(R.id.left_drawer);
ListView mDrawerListChild = (ListView) findViewById(R.id.left_drawer_child);

...

mDrawer.closeDrawer(mDrawerLinear);

(This is basically what @Karakuri posted, but with a more complete explanation and example.)

Yes it is possible to have any view as the sliding part of a drawer layout. I prefer declaring a FrameLayout as the drawer and replacing it with my fragment, and it runs just fine.

The error you are getting is probably due to some other reason in the Java part of your implementation.

Try moving android:id="@+id/left_drawer" to the LinearLayout instead of the ListView
